IMPROVEMENT IN'AVPPARATUS FOR DISTRIBUTING POWDER.

, Specification forming part of Letters Patent No. 197,601, dated November 27, 1877, application filed April l0, 1877.

To all whom it may concern:

Beit known that I, .Lines J. GAssrnY, of Boston, inthe county oi Suffolk and State of Massachusetts, have invented certain Improvements in Powder, of which the following is a specification:

In the accompanying drawing, forming a part of this speciiication, Figure l represents a vertical section of an apparatus embodying my invention. Fig. 2 represents a section on the line a, Fig. 1. y

This invention has for its obj ect to provide means for expelling any iinely-pulverized material or powder from the receptacle in which it is contained, and projecting said powder with a considerable degree of force from the receptacle by a blast of air, the invention being intended, mainly, for distributing insectdestroying powder.

It consists, essentially, in the combination, with a receptacle for powder or pulverized material, of an induction-tube adapted to admit a current or blast of air into the receptacle in such manner as to cause a violent agitation of the powder, and an eduction tube or passage adopted to permit the vescape of the air and the powder with which itis laden. The invention also consists in the details of construction of an apparatus embodying the above combination, and in the provision of an absorbent in the induction passage or tube to arrest the moisture of the breath when the blast of air is supplied by the lungs, and prevent the powder from being unduly moistcned, all of which I will now proceed to describe.

In the drawings, A represents a receptacle adapted to hold a powdered mixture or material. This receptacle may be of any desired form and size. I prefer to make it in the form of a can or jar having a large neck or mouth, which is provided with a stopper, B.

C1 represents the upper section of the induction-pipe, which enters the upper end of the receptacle A, and extends downwardly into said receptacle, this pipe being adapted to direct a current of air downwardly into or against the powder in the receptacle.

D represents the eduction-pipe, which constitutes a passage from the upper portion of Apparatus for Distributing.

the interior of the receptacle A to the external air, and projects from-the receptacle as far as is desired. When the apparatus is in working order the receptacle is air-tight at all points excepting where the pipes enter.

When a blast of air is forced through the pipe G2 it agitates and becomes charged or laden with the powder, and, in its escape from the receptacle, carries the powder with which it is laden through the pipe D, and projects it in a stream or jet from the receptacle a distance equal or proportioned to the powerfof the blast. The jet or cloud of vpowder thus produced may be allowed to fall on plants or,

forced into crevices or holes, for the purpose .of destroying insects or vermin, a suitable destructive powder being employed.-

If desired, the apparatus may be employed for propelling sand against van adhesivev surface, as in the ornamentation or sanding of walls.

The induction-pipe sections Ol C2 and the eduction-pipe D may be applied to the receptacle A in any desiredv manner, the chief requisites being that both pipes shall be connected with the upper part of the receptacle, so that the induction pipe shall direct the blast downwardly into or upon the powder, and the pipe D shall allow the ready escape ofthe powder-laden air, and that the receptacle shall be otherwise without communication with the outside air. y

In the present instance I have shown the apparatus as adapted to be used on a small scale, the blast being furnished by the lungs. For this purpose I provide the pipe O1 with a flexible extension, O3, of any desired length, its outer end being provided with a suitable mouth-piece. I make the stopper B hollow, and thus create a chamber or an enlargement of the induction-pipe, the latter being made in two sections, Cl O2, one of which is applied to the upper end of the hollow stopper, and the other to the lower end, as shown in Fig. l. Between these two sections I place an absorbent, E, of cotton or any material which will permit the passage of air, but will absorb and arrest the greater part of the moisture contained in air expelled from the lungs, thus preventing the powder in the receptacle from becoming unduly moistened. The lower section G2 projects above the bottom of the hol-rl low stopper, `and thus converts the latter into a drip-cup which accumulates the moisture collected by the absorbent.

P represents a partition in the hollow stopper, forming a space S, in the side of the stopper, which space is entirely distinct from Fig. 1. This form causes the powder-charged v air to escape with greater force, and to be projected farther from the receptacle than if the pipe D and space S were of uniform diameter.

The upper section G1 of the induction-pipe is attached to a screw-cap, which-is adapted to be detached from the stopper B.

The stopper may be secured to the receptaacle A by a suitable locking device, if desired. In theV present case I provide a compressible packing, K, which is interposed between the stopper and the mouth of the receptacle, and holds the stopper in place, and causes it to fit tightly.

vThis apparatus is especially valuable for throwing or distributing insect destroying powder, and with it a person can easily blow the powder several feet from the receptacle. The stopper B, having induction-pipes CRCZ and eduction-pipe D permanently attached to it, enables these pipes to be readily and conveniently applied to the receptacle. If desired, this stoppermay bemade without the lchamber and the space S, the induction and eduction pipes being conducted directly through it.

The apparatus may be made on a large scale, and adapted to be used for the wholesale de.- struction of potato-bugs, &c. In such case it would be desirable to supply the blast by a portable blower or bellows, and to provide several eduction-tubes.

I claim as my invention` l. An apparatus for distributing pulverized material or powder, vconsisting ofthe hollow or chambered stopper B, having inductionpipes C1 G2, absorbent E, and eduction-pipe D, in combination with the receptacle A, as

vset forth.

2. The stopper B, having the induction-pipes G1 G2, in combination with the absorbent E,

as set forth.

3. The hollow or ohambered stopper,hav ing the pipes C1 C2, absorbent E, space S, and pipe D, as set forth.

4. rlhe hollow or chambered stopper, having an absorbent, E, combined with the section C2 of the induction-pipe, said section prot jecting above the bottom of the stopper, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this. specification in the presence of two subscribing witnesses.
